A/C VOLTAGE BETWEEN ANY GROUND AND TV -Ground Loop?

Video Asylum

TVs, VCRs, DVD players, Home Theater systems and more.

With nothing hooked up to the Mitsu and power on, I put a DMM between the TV "F" or rca's and a house ground I get 57 VAC@60Hz. Switch polarity on meter - 34 VAC@60Hz
I have been tracing a ground loop hum coming from my Mitsu 55857. When any RCA's from a grounded source are hooked up one at a time the voltage drops until enough grounded RCA's are hooked up, reducing to 0 volts????
Only the Mitsubishi - 1 of 4 TV all on the same splitter, is putting out VAC.
The CATV cable will produce the same effects as the house ground. It appears the CATV is clean, as I checked it at the grounding block.
I have been butting heads with the mitsu tech for days. He claims it's a ground loop in the CATV - I say it's a floating gnd problem inside the tv or the power supply.
Any feedback would probably avoid an ulcer!
Thanks,
Mitch
